So, on another thread a person asserted that the green tabs under the "LSAT Document" section on the LSAT Status page of your LSAC account change to gray before the release, specifically at noon of the release date. Can anyone confirm this claim?

Within the old LSAC website, there was an "Update" box that would fill with text. When that contained text, the score release was imminent. You can see mine at the link below (and pardon the childish commentary in red - this is from my younger days).
